This shows, study a kind of cold-producing medium flow velocity that can make and increase, improve heat exchange property, the air-conditioner outdoor heat exchanger of enhancing productivity, this is the present technical issues that need to address of those skilled in the art.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of air-conditioner outdoor heat exchanger, makes cold-producing medium have higher flow velocity, improves heat exchange property, enhances productivity, and reduces cost.
In order to solve above technical problem, a kind of air-conditioner outdoor heat exchanger that the utility model provides, comprise heat exchanger assembly and discharge assembly, described heat exchanger assembly is provided with heat exchanging pipe and is used for compiling the part that confluxes of the fluid that flows out through heat exchanging pipe heat exchange effect, and described discharge assembly comprises for the gas collection branch road that connects heat exchanging pipe with for the discharge that delivers gas to the gas collection branch road.
Preferably, described heat exchanging pipe and gas collection branch road are many and corresponding setting one by one.
Preferably, be arranged on the length of heat exchanging pipe at heat exchanger assembly middle part greater than the length of the heat exchanging pipe that is arranged on the heat exchanger assembly two ends.
Preferably, described heat exchanging pipe comprises heat exchanger tube, stride pipe and three-way pipe, described heat exchanger tube, strides pipe and three-way pipe interconnects.
Preferably, described three-way pipe is pawl type three-way pipe.
Preferably, the described part that confluxes comprises that described three-way pipe is connected with drain pipe for the three-way pipe and the drain pipe that receive through the fluid of heat exchanging pipe heat exchange.
Preferably, described three-way pipe is U-shaped three-way pipe.
Compared with prior art, air-conditioner outdoor heat exchanger of the present utility model, comprise heat exchanger assembly and discharge assembly, because heat exchanger assembly is provided with heat exchanging pipe and is used for compiling the part that confluxes that flows out refrigerant, the discharge assembly is provided with discharge and the gas collection branch road that is used for being connected heat exchanging pipe, make fluid enter many heat exchanging pipes respectively through the discharge assembly, entering the part that confluxes again flows out, thereby compared with prior art, the utility model has improved stream according to the characteristic of axial flow blower, increase the heat exchanging pipe that confluxes, improve flow velocity, improve heat exchange property, improve heat exchange efficiency.
Description of drawings
Fig. 1 is the structural representation of air-conditioner outdoor heat exchanger of the present utility model under the embodiment refrigeration mode.
The specific embodiment
For those skilled in the art can understand technical scheme provided by the utility model better, below in conjunction with accompanying drawing, be described in detail by the specific embodiment.
See also Fig. 1, air-conditioner outdoor heat exchanger in the present embodiment, comprise heat exchanger assembly 3 and discharge assembly 4, heat exchanger assembly 3 is provided with heat exchanging pipe 1 and is used for compiling the part 2 that confluxes of the fluid that flows out through heat exchanging pipe heat exchange effect, discharge assembly 4 comprises that for the gas collection branch road that connects heat exchanging pipe with for the discharge 6 that delivers gas to the gas collection branch road heat exchanging pipe and gas collection branch road are many and corresponding setting one by one.Wherein heat exchanging pipe 1 comprises heat exchanger tube 7, strides pipe 8 and pawl type three-way pipe 9; The part 2 that confluxes comprises that three-way pipe is connected with drain pipe for the U-shaped three-way pipe (not marking in the drawings) and the drain pipe (not shown in the diagram) that receive through the fluid of heat exchanging pipe heat exchange; The gas collection branch road is divided into the first gas collection branch road 6, the second gas collection branch road 10, the 3rd gas collection branch road 11 and the 4th gas collection branch road 12.
Condenser or heater that air-conditioner outdoor heat exchanger in the utility model can be used as in the air-conditioning use, and under the air-conditioner refrigeration mode, heat exchanger is condenser; Under the air conditioner heat-production pattern, heat exchanger is evaporimeter.
Embodiment:
Under the air-conditioner refrigeration mode, become four gas collection branch roads of the refrigerant process discharge assembly 4 of HTHP to enter the heat exchanging pipe 1 on the top that is arranged in heat exchanger assembly 3 respectively through compressor compresses.Characteristics according to the distribution of axial-flow leaf air quantity, the upper and lower wind speed of heat exchanger assembly 3 is than higher, the middle part wind speed is lower, in order to make the condensation effect at top, bottom and middle part identical, refrigerant reaches when confluxing part 2 can reach identical temperature, and the heat exchanging pipe 10,11 flow process that is arranged on heat exchanger assembly middle part is longer than the heat exchanging pipe 6 that is arranged on the heat exchanger assembly upper/lower terminal, 12 flow process.
Arrow among Fig. 1 is the flow direction of refrigerant, refrigerant enters the heat exchanging pipe 1 on the top the heat exchanger assembly 3 from discharge 5 through the first gas collection branch road 6 and the second gas collection branch road 10, carry out condensation through heat exchanger tube 7 then, be flowed to pawl type three-way pipe 9, carry out super cooling effect and flow to U-shaped three-way pipe in the part 2 that confluxes simultaneously through striding pipe 8 again; Refrigerant enters the heat exchanging pipe 3 of the bottom the heat exchanger assembly 3 from discharge 5 through the 3rd gas collection branch road 11 and the 4th gas collection branch road 12, carry out condensation through heat exchanger tube 7, be flowed to pawl type three-way pipe 9, carry out super cooling effect and flow to U-shaped three-way pipe in the part 2 that confluxes simultaneously through striding pipe 8 again.The condensed refrigerant of above two-way is converging together from U-shaped three-way pipe, flows out from drain pipe.
The utility model has improved the structural limitations of the window air conditioner of outlet North America, under the state of the size of the bloated height of not changing heat exchanger and outdoor fan, increased the utilization ratio of outdoor heat exchanger, effectively increase the flow velocity of refrigerant in the pipe, increase the heat exchange effect, avoid use shunting capillary in production, the weldering that has solved the normal appearance of shunting capillary is blocked up, weldering is leaked, the problem of weldering mistake, and production efficiency is effectively improved.
